Title: New or improved process and apparatus for the extrusion of elongated articles havingprofiled heads
IPC: B21C25/08
Filed: 1952-12-30
Abstract: 731,723. Extruding. KREIDLER, A. Dec. 30, 1952 [Dec. 31, 1951], No. 32925/52. Class 83(4). A metal body having a profiled head 8 and an elongated shank 9 is produced in an extrusion press by forcing a billet through an extrusion nozzle 4 into a removable die 5, 5<SP>1</SP> which forms the head, and after removing the die, extruding the shank through the nozzle. The extrusion press, Fig. 3, has its punch 3 operated by a hydraulic motor whose cylinder 11 has supply and exhaust pipes 10, 12 respectively for pressure liquid, controlled by valves 13, 14 respectively. These valves are operated by a common spindle 15 connected through a pinion 21 and rack 20 with a servomotor piston 18 biased by a spring 19 and subjected to the extrusion pressure in the supply pipe 10. The removable die comprises two parts 5, 5<SP>1</SP> slidable on a table 6 into closed and open positions by hydraulic motors 23, 23<SP>1</SP> respectively, controlled by a reversing slide-valve 24. The pressure in the supply pipe 10 during the filling of the die 5, 5<SP>1</SP> is insufficient to move the piston 18 against its spring. When the die is filled, however, this pressure rises and moves the piston 18 and rack 19 to the left thereby closing the valves 13, 14 to stop the press, and moving the slide 25 of the reversing valve 24 which causes the motors 23, 23<SP>1</SP> to open the die. This causes a reduction of pressure in the pipe 10 whereby the spring 19 returns the piston 18 and opens the valves 13, 14; the extrusion process then recommences. The die is closed by moving a handle 26. The opening movement of the die 5, 5<SP>1</SP> may alternatively be controlled by mechanical, electrical or pneumatic means responsive to the extrusion pressure.

Abstract: 339,067. Dyckerhoff, E. Oct. 30, 1929. Nonconducting coverings for heat.-Peat and like material is treated to render it substantially fireproof and non-smouldering by boiling it and treating with fireproofing chemical solutions. Crude peat or marshy turf is charged into a container which is closed and heated under pressure to 100‹ C. or more. Before or during boiling, dilute phosphoric acid or other fireproofing chemical is added, and the peat is finally pressed, dried, and treated in any known manner for the manufacture of peat meal or shaped or pressed articles. The proportion of water in the crude material is preferably reduced before treatment, e.g., by adding a proportion of dry peat obtained in this process, in order that the fireproofing solution subsequently removed shall not be too dilute for use again.
